Analysis and Improvement Measures of Die-cover Accident in Well-type Reheating Furnace
Well-type reheating furnace is one of the important equipments in iron and steel enterprises. In order to make iron and steel products in sufficient heat treatment effect before delivery in the reheating process, it is more and more widely used in todays domestic steel processing enterprises. It is one of the key equipments for stable product quality, which makes it an important equipment in the production of iron and steel enterprises.
However, the risk of die-covering accident cannot be ignored. Under certain conditions, the material in the furnace will be spitted or pinched into the die-cover, causing the die-cover to be unable to open, resulting in serious damage to the furnace. Therefore, it is of great significance to analyze the causes of die-cover accident in well-type reheating furnace, so as to provide effective measures to prevent the occurrence of die-covering accidents.
In general, the die-covering accident of well-type reheating furnace is caused by the dislocation of the furnace wall and the absence of the sand sealing layer. When the steel material is spitted or pinched into the die-cover, the dislocation of the furnace wall will cause the material to enter the die-cover, causing the damage of die-covering accident. In addition, due to the lack of sand sealing layer in some old-fashioned well-type reheating furnaces, the gap between the gate and the die-cover is too large to be blocked by the sand, making it difficult to block the material from entering the die-cover.
In order to prevent die-covering accident in well-type reheating furnace, it is important to pay attention to the following aspects:
1. Strengthen the management of well type reheating furnace. It is necessary to frequently inspect the well type reheating furnace, and timely adjust the slag groove to ensure the normal operation of the furnace;
2. Regulate the operation of the furnace. In order to prevent the slag groove displacement, when removing the slag, the large-sized slag and other sundries should be removed first, and the small-sized slag should be removed after the furnace temperature has been lowered;
3. Strengthen the maintenance of the well-type reheating furnace. The furnace should be inspected regularly for wear and tear, the sand sealing layer should be repaired in time, and the gap between the door and the die-cover should not be too large;
4. The workers should be trained and educated about the safe operation of the furnace. The induction furnace technicians should master the related knowledge of well-type reheating furnace, grasp the operation conditions of the furnace, and raise the awareness of safety operation;
5. Use automated well type reheating furnace with backup functions.Adopting advanced automatic well type reheating furnace can greatly improve the safety of operation, reduce the labor intensity of workers, simplify the control and improve the work efficiency.
The above are some of the improvement measures that can be used to prevent die-covering accident in well-type reheating furnace. It should be noted that to effectively prevent the occurance of die-cover accident, we should work together and implement the measures together. Only by improving the operation and maintenance management level of the well-type reheating furnace, can we truly achieve the purpose of preventing die-cover accident.
